Improvement in corn-planters



NITED STATES LAWRENCE ROERIG, OF VVINNEBAGO AGENCY, MINNESOTA.

IMPROVEMENT IN CORN-PLANTERS.

Specification forming part of Letters Patent No. 146,477, dated January 13, 1874; application filed November 1, 1873.

To all whom it may concern:

Be it known that I, LAwRENoE Ronnie, of Winnebago Agency, in the county of Blue Earth and State of Minnesota, have invented a new and valuable Improvement in CornPlanters; and I do hereby declare that the Tfollowing is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation oi' a sectional view oi' my corn-planter. Fig. 2 is a rear view of the same. Figs. 3 and 4.- are detail views.

This invention relates to improvements in corn-planters, wherein the grains of corn are discharged in regulated quantities from hoppers by means of tappets on a transportingwheel acting on a seed-slide, the grains being conducted from the hoppers into the ground through flexible tubes connected to drillopen ers. `My invention consists in a novel means for regulating the depth for receiving the shovels or drill-teeth, which are applied to hinged drag-bars, as will be hereinafter explained.

.Thefollowingis a description of my improvements:

In the annexed drawings, A A represent two transportingwheels, which are applied on short axles` secured to ends of an axle-tree, B.

' C is a drafttongue, which is rigidly secured to the axle-tree at the middle of its length; and E is a hopper-box, which is constructed with several hop ers having inclined sides. This hopper-box 1s hinged tothe iront edge of the axletree, and securedby hasps and staples, or by hooks, to the back of this axle-tree. The upper side of the axle-tree Bis grooved longitudinally, and into the groove a perforated seed-slide, b, is iitted to receive endwise movement. Through one end of this slide b a spring, S, is applied for moving it in one direction, and to the other end of this slide a pin is fixed, which passes through a vibrating slotted arm, Z, that is pivoted to a bracket, l', on the end of thehopper-box E next the wheel A. There is pivotcd loosely to the pin, to which arm lis keyed, a right angular jarm, w, having a tongue, fw, on one end, which arm is connected by a chain, p', to a lever, p. `This lever p is pivoted to the end of hopper-box E, and held against the msame by a spring, fr. Between the two arms l and fw a spring, 2is applied, and its ends bent so as to hold the arm w out in a position to be struck by tappets a' on a ring, a., which is secured to the inner side of wheel A. The curve F2 is designed to be of an eccentric shape, to prevent the pressure on the plow from throwing it upward without depending on frictional contact alone. When lever p is raised and adjusted on a pin, 3, the arm w will be drawn in out of the range of the tappets a', and the slide b will not be moved. When the machine is moved backward, the spring 2 will allow the arm w to yield when struck by the tappets without deranging the parts. D D D represent dragbars, which are pivoted to a rod, t, beneath the axle-tree B, and extend out in rear thereof, and are seliadjusting vertically. To each one of these bars D an open standard, F, is connected by a pivot, u, and tothe front angle of this standard a shovel, F1, is secured, in rear of which are covering-wings J. Each standard F is applied to a slot made vertically through its bar D, at the rear end of which slot is an adjusting-screw, m, which is tapped through the rear end of the bar, so as to bear against the rear curved end F2 of the standard, as shown in Fig. l. It is by means of the screws m and the curved ends F2 of the standards F that the depth required for the shovels to run in the ground can be regulated. The drag-bars D are connected, by means of `chains f and bails y, to grooved segments g on a horiA` zontal transverse rod, f, which has its bearings in brackets e, secured to the rear side of axletree B. G is a hand-lever, which is pivoted on the rod f alongside of a ratchet-wheel, g', which is keyed on this rod. A pawl, t, is pivoted to the lever G, for engagement with the ratchet-wheel g', which pawl is connected by a rod, i', to a key lever, j, acted on by a spring, and arranged near the free end of lever G. By vibrating this lever G, the dragbars D can be raised and the shovels lifted free from the ground. The grains of corn are conducted from the hoppers through flexible tubes s, and discharged in rear of the shovels F1 into the ground, and, by means of slides c, the discharge can be regulated.

What I claim as new, and desire to secure The standards F, carrying shovels F1 an coverers J and constructed With rear curved ends F2, in combination with setscreWs m and drag-bars D, as and for the purposes described. In testimony that I claim the above I have hereunto subscribed my name in the presence of two Witnesses.
